The Zeroaccess (Sirefef) root kit has become very wide spread in the past few months. It's may be detected by your antivirus utility as, “Virus.Win64.ZAccess.a”, “Generic.dx!Bfnd”, “Virus:Win64/Sirefef.A”, “Trojan.Zeroaccess!Inf4” or “PTCH64_SIREFEF.A”. It's spread by many different techniques, but we've mainly come across computer systems that were infected with it, because the user downloaded and executed some bogus free software tools, software cracks or keygenz for a wide range of applications. Once your computer is infected with this rootkit, you may receive a warning from Google Chrome that states “ The server's security certificate is revoked”, when you try to access certain websites. Or you may notice that when you open a web browser on the infected system , that you are redirected to various advertising sites such as, "happili.com" and "searchnu.com". If you search for things online, from those sites or not, you start to receive abnormal results, such as more advertising sites, shopping sites, free computer cleaning tools results and just possibly porn video sites being displayed.
This particular root kit also represents a serious threat to your personal information and passwords. So you'll need to keep a close eye on your online accounts for suspicious activity once you have successfully removed Zeroaccess (Virus:Win64/Sirefef.A).
Before you start, we suggest that you back up your important data to usb flash drive or some other external media. Also, you should have your original operating system installation discs or your system restore discs handy, because you may need to use them afterwards to repair your Microsoft Windows installation after this rootkit has been removed from your computer.
Now, to download the necessary files that you will need to clean your system of the infection, you may need access to an alternate computer that hasn't been infected by the Zeroaccess rootkit. Since "Trojan.Zeroaccess!inf4" will most likely keep redirecting your browser when you attempt accessing any software security related sites such as, Symantec's and McAfee's sites.
To complete the repair you will need to download:
You may also possibly need your original operating system installation disks, because you may need to repair your Microsoft Windows installation after removing this particular rootkit.
